IPC: H01B13/16
Filed: 1981-03-11
Abstract: PURPOSE: To produce an anodized film having high heat conductivity, resistance to heat and electrical insulating properties, by anodizing an Al material or an Al alloy material in an electrolytic cell containing NH 4  salts or Na salts, and polymerizing a polymerizable organo-metallic compound that has been impregnated into the fine pores or the surfaces of the resulting anodized film.  
     CONSTITUTION: An Al alloy plate, particularly Al-Si alloy plate is anodized in an electrolytic cell containing an NH 4  salt (for example: ammonium tartrate) or an Na salt (for example: NaOH). In this electrolytic cell, preferably having a concentration of 5W80g/l NH 4   + , and that of 1W30g/l Na + , 5W40°C cell temperature, and 0.5W20A/dm 2  electric current density. A polymerizable organic metal compound (for example: phenyltriethoxy silan) solution is impregnated into the pores or the surface of the thus resulting anodized film. Then the anodized film is dried to eliminate excess water and organic solvents, and the adhered polymerizable organo-metallic compound is polymerized by polymerizing means such as heating.

Title: Indentation pattern forming method
Inventor: HAINTSU YURUGEN YAKOBU
IPC: B23K26/40
Filed: 1993-02-25
Abstract: PURPOSE: To improve environmental aspect and cost performance by controlling energy supply to a heating spot so that the melting temperature of a workpiece material is not reached, while nevertheless the sublimation temperature of the oxide formed by the heating is exceeded. CONSTITUTION: The material of a workpiece 1 is oxidized at the heating spot 8, while the oxide so formed is sublimed and detached from the cavity without melting. The reason is that the energy supply is controlled in such a manner as the melting temperature is not reached while the sublimation temperature is exceeded. In the case of molybdenum or a molybdenum alloy, melting of the material needs a high temperature power because of the extremely high melting temperature. Accordingly, a small amount of energy is supplied, enabling only the oxidation and the subsequent sublimation to be caused as a result. Therefore, the method is applicable to a workpiece made of molybdenum or a molybdenum alloy whose melting point is higher than the oxidation temperature and the subsequent sublimation temperature.  Since the material removed by sublimation is generated merely as a gaseous oxide, there is little effect on the environment.
